Getting proper rest is one of the biggest challenges for truck drivers. Long routes, tight delivery schedules, and nights spent in the sleeper berth often add up to years of insufficient sleep—sometimes without drivers realizing the impact it has on their long-term health. And science is increasingly pointing to a concerning connection: chronic poor sleep may raise the risk of developing Alzheimer’s disease and other forms of dementia later in life.

What happens in the brain when we don’t sleep well?

During deep sleep, the brain activates a “cleaning” mechanism known as the glymphatic system. This system removes toxins and proteins such as beta-amyloid and tau—key markers directly linked to the development of Alzheimer’s.

When someone sleeps too little or experiences frequent interruptions, this system becomes less effective. Over time, those proteins begin to accumulate, impairing memory, concentration, and—according to multiple studies—significantly increasing the risk of cognitive decline. In other words, every poorly slept night leaves a trace.

The trucker lifestyle: a risky combination

Heavy-duty trucking brings together several conditions that disrupt quality sleep:

• Irregular schedules and overnight shifts that throw off the body’s natural rhythm

• Sleeping in noisy or uncomfortable cabins, making deep sleep harder to achieve

• Constant stress from deadlines, delays, or fear of fines

• A higher prevalence of sleep apnea—disrupted breathing that reduces sleep quality

In California, even though federal Hours of Service (HOS) rules mandate minimum rest periods, work pressure often leads drivers to sleep less than recommended. Combined with other health factors common in the industry—hypertension, diabetes, obesity, and smoking—the neurological risk becomes even greater.

What can drivers do today?

Getting 7 to 9 hours of quality sleep whenever possible is one of the best investments in long-term brain health. It’s also crucial to address loud snoring or breathing pauses (possible sleep apnea), cut back on stimulants, maintain healthy habits, and make the most of mandatory rest breaks.

Good sleep doesn’t just help prevent accidents—it may also protect your memory for years to come.
